[Elecraft] XV50 Rev B - Questions

[Don Wilhelm]

Brian,

In later XV transverters, JP9 controls when the crystal oven is powered.
Since you do not have JP9, even if you have a crystal oven, it will 
still work fine.
The oven will be powered when the XV50 is powered.  Just allow some time 
for it to warm up (about 20 minutes).
Actually, the 22MHz crystal does not drift much and usually does not 
require the oven.

73 and Happy Thanksgiving,
Don W3FPR
